Aerodynamics is a branch of mechanics that studies the motion of air and its interaction with solid bodies. The effect of moving air on airframes is crucial in designing aircraft, and it is no wonder that the science of aerodynamics was developed as part of the effort to construct a high-performance airplane. It is also natural that modern states, recognizing airplanes' military significance, have taken a great interest in aerodynamics. But how does research and development of this kind proceed? How are science and engineering related to each other, particularly in government research programs? The present book provides some insights into these questions.
